The candidates scheduled to participate are all declared presidential candidates except Bachmann, a U.S. representative from Minnesota who has said she’ll announce her intentions in Waterloo shortly.

The tour, which ends July 2 in Des Moines, is being organized by the tea party in cooperation with American Principles in Action, the Innocence Project and the Leadership Institute.

The Washington, D.C.-based American Principles in Action stresses ideals in the Declaration of Independence including that “all men are created equal, endowed by our creator with certain unalienable rights, and among these are life, liberty, and the pursuit of happiness.”
